The Silent Film Director app for iPhone lets you create Silent Films and Retro Music Clips masterpieces.

“The app is available in Standard and Pro versions. With the Standard version, you can record or upload video and render it with a variety of video effects (including Black & White, ’70s Home Video and Sepia), add a soundtrack (default, or your own), and adjust the playing speed and quality of the video. With the Pro version, you get additional advanced features like title cards and transitions, and the ability to mix photos and video with separate effects.”
